LoopPlay vs MetroNova

Practice at your own pace, in your key, on iPhone and iPad. LoopPlay helps you work through a difficult passage, learn a song by ear, or practice a phrase in another language. Open your own audio files, repeat the part you need, and use Pro to adjust speed and pitch independently. [A-B Loop & Saved Points] Set a start point (A) and end point (B) to repeat a section. Your loop points are saved per file and restored when you open it again. [Speed Control] Slow down a passage without changing its pitch, or speed it up as you improve. Choose from three free speed presets: 0.95x, 1x, and 1.05x. Pro unlocks speed adjustment from 0.5x to 2.0x. [Pitch Control — Pro] Transpose audio from −12 to +12 semitones without changing playback speed. Match a song to your vocal range or practice in a different key. [Waveform & BPM] Use the waveform to find a passage and adjust your loop. Pro detects BPM and lets you set a target tempo for practice. [Playlists & Recent Folders] Open audio files or folders, reorder tracks, and return to recent folders. Your custom track order is saved for each folder. [Practice Controls] Switch between playback, loop, speed, pitch, and BPM tools in the bottom controls. Pitch and BPM tools require Pro. [Lock Screen & Control Center] Control playback from the lock screen and Control Center. See track artwork when it is available in your audio files. [Free & Pro] Playback, A-B looping, saved loop points, playlists, recent folders, and the 0.95x, 1x, and 1.05x speed presets are free. A one-time Pro purchase unlocks 0.5x–2.0x speed control, pitch control, and BPM detection. No subscription. Existing paid users receive Pro automatically.
